YARN-SEPARATOR FOR SPINNING-=FRAMES.

SFBCIPICAIION forming part of Letters Patent No. 380,6d4, dated April 3, 1888.

Application tiled January 7, 1888. Serial No. 260,029. (N'o model.)

To all whom it may concern:

Be it known that 1', HENRY C. CUNNING- HAM, of lilanchcster, county of Hillsborough, State of New Hampshire, have invented an Im- 5 provement in. YarnSeparators for Spinning- Franies, of which the following description, in connection with the accompanying drawings, is a specification, like letters on the drawings representing like parts.

IO My invention relates to adevice for operat ing the separators or guard-plates employed on spinning-frames topreventinterference be tween the threads passing to differentspindles.

Heretoforc the separator-plates have been attached to a bar or shaft pivoted at the rear of the spindles, so that the separator-plates may extend forward between the spindles when the ring-rail is at the lower part of its traverse, or may be turned up vertically at the rear of the spindles when the ring-rail is at the upper part of its traverse. The weight of the separators was only partially counterbalanced, so that the separators tend by gravity to turn to the horizontal position and are raised by the direct engagement of the ringrail as it rises in its traverse, and the greater part of the weight of the separators in such construction is incumbentupon the ring-rail during the middle and upper part of its traverse, which is obj ectionable.

The present invention consists, mainly, in providing means for positively turning the separators down into their horizontal position, said separators being almost entirely counterbalanced, so that they will not turn down under the action of gravity, and do not offer any appreciable resistance to the ring-rail as it moves upward in its traverse,,the main portion of the work of turning the separators taking place in the downward movementof the ring-rail,whcn the resistance of the counter-weight of the separators tends merely to counterbalance a part of the weight of the ringrail, which is in no way objectionable.

Figure l is a vertical section of a portion of a spinningirame, showing the supportinghanger and lever for the separator-bar and one of the separators and the device for turning them into the horizontal position in side 50 elevation; and Fig. 2 is a front elevation of one of the hangers for the separator-bar and a portion of the supporting-lever for said bar, and one of the separators and the actuatingfinger for the separator-bar, with the separator in the vertical position.

The separator a may be of usual construction and in the usual relation to the spindles b, ring-rail c, and roller-beam or top board, (if, of the spinning-frame, the said separators a being connected with a bar, 6, extending along at the rear of the spindles and connected with two or more levers, f, pivoted on brackets or hangers 9, connected with the top board, at, so that the said separators may extend forward in a substantiallyhorizontal position, as shown in full lines, Fig. 1, whenthe ring-rail is near the lower part of the spindles, or may be turned up nearly to the vertical position, as shown in dotted lines, Fig. 1, to permit the free movement of the ring-rail when near the upper part of the spindles.

The supporting-levers f for the separators are provided with heavy counter-weights h, which nearly or wholly counterbalance the weight of the separators, so that the latter will 7 5 remain in whatever position they may be turned to until positively moved from that position.

In order to turn the separators to the horizontal position when the ring-rail is in position for filling the lower part of the bobbin, which is the time when the separators are required to prevent interference between the threads, the separator-bar e is provided with one or more actuating projections or fingers, z, which are nearly at right angles to the separators, so that when the separators are in the vertical position the said fingers project forward beneath the ring-rail, as shown in dotted lines, Fig. 1, so that when the latter is moved o down-toward the lower part of the spindles it will engage the said fingers and turn the separators from the dotted to the full line position,

as will be readily understood from Fig. 1, and the said fingers will serve to positively retain 5 the separators in the horizontal position as long as the ring-rail remains near the lower portion of the spindles. The hanger g is continued below the fulcrum for the lever f to form a stop projection, g, that engages the end of the lever f and prevents the separators from falling below the horizontal position.

When the ring-rail, moving upward, engages the separators, the latter afford scarcely any resistance to the upward movement, and when lifted a short distance do not necessarily return as the ring-rail moves down, but are again moved farther up at the next upward movement of the ring-rail. The ring-rail is thus relieved from downward and lateral pressure that tends to wear its supporting-posts and throw the rings out of line, and the separators are positively brought into position when required by the agency of the actuating-fingers i and ring-rail.

The apparatus operates equally well when the ring-rail traverses the entire length of the bobbin or when it has a short traverse at different parts of the bobbin successively.

I claim 1. The combination of the separators and their pivoted support with an actuating projection adapted to be engaged by the ring-rail HENRY C. CUNNINGHAM.
